On-line editing and data conveying media for edit decisions

Abstract

Frames of image data (FIG. 5 ) are conformed from source material in response to an edit decision list (FIG. 2 ). Some of the image data is modified in an on-line environment (FIG. 3 ) and an output tape is produced including said modified frames. An output edit decision list (FIG. 7 ) is generated with conventional editing references (SRC, HINT) to the output tape. In addition, reference to the original source material are also included, encoded as comments.

What we claim is:  
     
       1. A method for on-line editing, comprising: 
       (a) modifying, in an on-line editing environment, one or more frames of machine-readable image data from a source in accordance with a first edit decision list;  
       (b) producing, in the on-line editing environment, machine-readable video output comprising the one or more modified frames and;  
       (c) producing, in the on-line editing environment, a second edit decision list, wherein said second edit decision list is readable by a conventional on-line video editing system and comprises:  
       (i) conventional on-line editing information for the contents of the video output; and  
       (ii) one or more encoded references to the image data from the source that was used to produce the video output, wherein said encoded references are configured to be ignored as a comment of said second edit decision list when processed by a conventional on-line video editing system and to be used in said on-line editing environment to derive said first edit decision list and make reference to the original source material.  
     
     
       2. The method of  claim 1  further comprising writing the second edit decision list to a data carrying medium. 
     
     
       3. The method of  claim 1  wherein the references to the image data from the source comprise comments. 
     
     
       4. The method of  claim 1  wherein the one or more modified frames are stored on an array of magnetic discs. 
     
     
       5. The method of  claim 1  further comprising generating, in the on-line editing environment, new machine-readable source material that is produced into the video output. 
     
     
       6. The method of  claim 1  wherein the references to the image data from the source identify a position of clips in the source. 
     
     
       7. The method of  claim 1  wherein the references to the image data from the source comprise capture hints for capturing portions of one or more frames from the source. 
     
     
       8. The method of  claim 7  wherein: 
       the modifying of the one or more frames results in a clip having a duration; and  
       the capture hints comprise handles, effectively extending the duration of the clip beyond the duration included with the modification of the one or more frames.  
     
     
       9. The method of  claim 1  wherein the on-line editing environment provides for modifying the one or more frames from the source at full resolution. 
     
     
       10. The method of  claim 1  wherein the first edit decision list was created in a non-linear editing environment. 
     
     
       11. An on-line video editing apparatus comprising a video editing means configured to: 
       (a) modify, in an on-line editing environment, one or more frames of machine-readable image data from a source in accordance with a first edit decision list;  
       (b) produce, in the on-line editing environment, machine-readable video output comprising the one or more modified frames;  
       (c) produce, in the on-line editing environment, a second edit decision list, wherein said second edit decision list is readable by a conventional on-line video editing system and comprises:,  
       (i) conventional on-line editing information for the contents of the video output; and  
       (ii) one or more encoded references to the image data from the source that was used to produce the video output, wherein said encoded references are configured to be ignored as a comment of said second edit decision list when processed by a conventional on-line video editing system; and  
       (d) use, in the on-line environment, said encoded references to derive the first edit decision list and refer to the original source material.  
     
     
       12. The apparatus of  claim 11  further comprising an output means configured to write the second edit decision list to a data carrying medium. 
     
     
       13. The apparatus of  claim 11  wherein the references to the image data from the source comprise comments. 
     
     
       14. The apparatus of  claim 11  wherein the one or more modified frames are stored on an array of magnetic discs. 
     
     
       15. The apparatus of  claim 11 , the video editing means further configured to generate, in the on-line editing environment, new machine-readable source material that is produced into the video output. 
     
     
       16. The apparatus of  claim 11  wherein the references to the image data from the source identify a position of clips in the source. 
     
     
       17. The apparatus of  claim 11  wherein the references to the image data from the source comprise capture hints for capturing portions of one or more frames from the source. 
     
     
       18. The apparatus of  claim 17  wherein: 
       the modifying of the one or more frames results in a clip having a duration; and  
       the capture hints comprise handles, effectively extending the duration of the clip beyond the duration included with the modification of the one or more frames.  
     
     
       19. The apparatus of  claim 11  wherein the on-line editing environment provides for the video editing means to modify the one or more frames from the source at full resolution. 
     
     
       20. The apparatus of  claim 11  wherein the first edit decision list was created in a non-linear editing environment. 
     
     
       21. A data conveying medium having data encoded thereon, the data representing a second edit decision list produced in an online editing environment, the second edit decision list comprising: 
       conventional on-line editing information for the contents of one or more modified frames, wherein the one or more modified frames were modified in an online editing environment from source image data in accordance with a first edit decision list; and  
       one or more encoded references to the source image data, wherein said encoded references are configured to be ignored as a comment of said second edit decision list when processed by a conventional on-line video editing system and to be used in said on-line environment to derive said first edit decision list and make reference to the original source material.  
     
     
       22. The data conveying medium of  claim 21  wherein the encoded references to the source image data are encoded in comments. 
     
     
       23. The data conveying medium of  claim 21  wherein the references to the source image data identify a position of clips in the source image data.
